' (Granted This invention relates to devices for de-podding or shelling peas and has for its object to provide.

an apparatus by whichrpeas may be rapidly and effectively removed and separatedfrom their pods without slow tedious individual handfeeding of the peas to the apparatus. The invention also has for its object to provide a comparativelysiinple apparatus the parts of which may be easilyV and:

device which forces them to the rollers. desired more than one feed device may be used.

When passed through the rollers the pods burst open and discharge lthe peas backuponV the belt. In another form the feed deviceais located in a feed hopper into which Athe peas are delivered and from which they pass to the belt'adjacent to 'the rollers. In a further form a plurality of feed de vices are located in a hopper. By the use of a hopper containing a feed device the pods arev wholly or partially broken open before reaching thebelt. When either a single feed device ora plurality of feed devices are used, the peas,Y which vary, are intended to vbe de-podded in thehopper and discharged therefrom upon the belt. then pass through theholes in Athe belt whilev the pods are delivered to and pass between the pair of rollers.V Should any filled or partially filled pods reach the rollersfrom the hopper, the peas will beejected by the squeezing action of the rollers, but primarily in the hopper form of the appa-r ratus the belt and rollers function to separate the peas from the pods which already have been emptiedin the hopper.

-In the embodiment shown in Figure 12` the peas to be podded are stored inthe tray 66 and fed by hand into the hopper 62. YThe `feed device 48 is rotated by toothed gearing as previously described.A The unshelled peas are driven by the vanes 59 of the device 48 against the rubberV lining E4 and burst open and'discharge' the `peas upon the belt 20. holes in the belt. The empty pods are fed onward by the belt and pass beneath the roller 4|. The belt and rollers, therefore, function 4to separate the peas (ejectedin the hopper) from the empty pods, but should any pods still 4contain peas when the rollers arereached, the latter will eject the peas from the pods by thesqueezing action. The hopper may be swung upon itspivot G3 to adjust its relationship with the belt -2,'if desired, and it may be formed in halves bolted together to ensure easy dismantling and' assembling, but it will be found advantageous to increase the number of vanes carried by the feed device i8 up to double the number shown in the drawings. The hopper feed is quite eicient.

In the embodiment shown in Figure l5 it will be seen that unshelled peas arerst driven by the upper feed device 48 against the lining 13. They are discharged to the oppositely rotating lower feed device and are driven against the lining 16. The smaller vanes 12 of the upper device assist in breaking open the pods and in discharging them. The lower device is driven by the toothed pinions already described. The upper device 48 is rotated by a spur wheel engaging the pinion 4S of the lower feed device. The upper feed device preferably rotates at a reduced speed. The pods are opened completely by the two feed devices. The peas are discharged upon the belt 20 and pass through its holes 2| whilst the empty pods pass beneath the squeezing roller 4l.
